帮忙看一下这段asp代码错在那里

if request("action")="reg" then
set rs=server.CreateObject("adodb.recordset")
rs.open "select * from user where 易做图='"&trim(request("易做图"))&"'",conn,1,1
if rs.recordcount>0 then
response.write "<Script language='JavaScript'>window.alert('您输入的域名已存在，请返回重新输入！');history.back(-1);</Script>"
response.End()
end if

sql="select * from user"
set rs=server.createobject("adodb.recordset")
rs.open sql,conn,1,3
rs.addnew
rs("names")=trim(request.Form("name"))
rs("pwd")=trim(request.Form("pwd"))
rs("wenti")=trim(request.Form("wenti"))
rs("易做图")=trim(request.Form("易做图"))
rs.update
rs.close
set rs=nothing
response.write "<script language=javascript> alert('注册成功，点击确定立即登录！');location.replace('login.asp');</script>"
response.end
End if
end if
%>

答案：
以前的代码杂乱无章，我帮你重新写了下。
试一下看看，如果不行就联系我。

<!--#include file="conn.asp"--> 
<% 
if request("action")="reg" then 
set rs=server.CreateObject("adodb.recordset") 
rs.open "select * from user where name='"&trim(request("name"))&"'",conn,1,1
if rs.eof or rs.bof then
rs.close
rs.open "select * from user where 易做图='"&trim(request("易做图"))&"' and name<>'"&trim(request("name"))&"'",conn,1,3
if rs.eof or rs.bof then
rs.addnew
rs("names")=trim(request.Form("name")) 
rs("pwd")=trim(request.Form("pwd")) 
rs("wenti")=trim(request.Form("wenti")) 
rs("易做图")=trim(request.Form("易做图")) 
rs.update 
rs.close 
set rs=nothing 
response.write "<script language=javascript>alert('注册成功，点击确定立即登录！');location='login.asp';</script>" 
else
rs.close
response.write "<Script language='JavaScript'>alert('您输入的域名已存在，请返回重新输入！');history.go(-1);</Script>" 
end if
else
rs.close
response.write "<Script language='JavaScript'>alert('您输入的用户名已存在，请返回重新输入！');history.go(-1);</Script>" 
end if
end if 
%> 
第三行起
if request("action")="reg" then 
set rs=server.CreateObject("adodb.recordset") 
rs.open "select * from user where name='"&trim(request("name"))&"'",conn,1,1 
if rs.recordcount>0 then 
response.write "<Script language='JavaScript'>window.alert('您输入的用户名已存在，请返回重新输入！');history.back(-1);</Script>" 
response.End() 
end if
删除掉,,,重复啦
另外 最后一个 end if 删除
<!--#include file="conn.asp"--> 
<% 
if request("action")="reg" then 
set rs=server.CreateObject("adodb.recordset") 
rs.open "select * from user where name='"&trim(request("name"))&"'",conn,1,1 
if rs.recordcount>0 then 
response.write "<Script language='JavaScript'>window.alert('您输入的用户名已存在，请返回重新输入！');history.back(-1);</Script>" 
response.End() 
end if
 rs.close
set rs=nothing
set rs=server.CreateObject("adodb.recordset") 
rs.open "select * from user where 易做图='"&trim(request("易做图"))&"'",conn,1,1 
if rs.recordcount>0 then 
response.write "<Script language='JavaScript'>window.alert('您输入的域名已存在，请返回重新输入！');history.back(-1);</Script>" 
response.End() 
end if 
 rs.close
set rs=nothing

sql="select * from user" 
set rs=server.createobject("adodb.recordset") 
rs.open sql,conn,1,3
rs.addnew 
rs("names")=trim(request.Form("name")) 
rs("pwd")=trim(request.Form("pwd")) 
rs("wenti")=trim(request.Form("wenti")) 
rs("易做图")=trim(request.Form("易做图")) 
rs.update 
rs.close 
set rs=nothing 
response.write "<script language=javascript> alert('注册成功，点击确定立即登录！');location.replace('login.asp');</script>" 
response.end 
End if
